@metaharness/host-pi-dev

pi.dev coding agent host adapter for the agent-harness-generator project.

NOT Inflection's Pi.ai consumer chatbot. This is the badlogic/pi-mono Pi coding agent — a minimal CLI agent harness.

Generates the host-specific files a Pi-targeted harness needs:

• A Pi extension TypeScript source that registers each kernel tool via pi.registerTool({...})
• AGENTS.md with the harness's agent roster
• SYSTEM.md with the harness's system prompt

Critical design note

Pi explicitly ships with no MCP. From the README's "What we didn't build" section: "No MCP. Build CLI tools with READMEs (see Skills), or build an extension that adds MCP support."

This adapter generates a Pi extension (TypeScript module installed via pi install npm:@your-org/your-harness), NOT MCP config. The kernel's MCP primitives are bypassed; the tool registry is exposed via pi.registerTool({...}) calls.

Usage

import adapter from '@metaharness/host-pi-dev';

const config = adapter.generateConfig({
  name: 'my-bot',
  tools: [{ name: 'remember', description: 'Store a memory', inputSchema: {} }],
  agents: [{ name: 'coder', systemPrompt: 'You are a coder.' }],
});
// config['pi-extension/src/index.ts'] = '<TypeScript>'
// config['AGENTS.md'] = '<markdown>'
// config['SYSTEM.md'] = '<markdown>'
